All our efforts in the https://www.wowhead.com/zone=10425/the-eternal-palace finally pays off with the "defeat" of https://www.wowhead.com/npc=155126/queen-azshara and the plan of Sylvanas being revealed along side with N'zoth being freed. Also, this time we did not build a snowman (https://www.infinite-guild.eu/upload/smfpics/bfa/bod/jainambig.jpg).
Congratulations to everyone that helped.
